DESCRIPTION
Product description:
- Operation of the product is simple and convenient.
- The product is small in volume, light in weight (total weight is about 50g including batteries) and convenient in carrying.
- Power consumption of the product is low and the two originally equipped AAA batteries can be operated continuously for 20 hours.
- The product will automatically be powered off when no signal is in the product within 5 seconds

Salient features:
- Display Format: OLED Display;
SpO2 Measuring Range: 0% - 100%;
Pulse Rate Measuring Range: 30 bpm - 250 bpm;
Pulse Wave Display: columiation display and the waveform display.
- Power Requirements: 2 ×1.5V AAA alkaline battery(or using the rechargeable batteryinstead), adaptable range: 2.6V~3.6V.
- Power Consumption:Smaller than 30mA.
- Resolution: 1% for SpO2 and 1 bpm for Pulse Rate.
- Measurement Accuracy: ±2% in stage of 70%-100% SpO2, and meaningless when stage being smaller than 70%. ±2 bpm or±2% (select larger) for Pulse Rate.
- Measurement Performance in Weak Filling Condition: SpO2 and pulse rate can be shown correctly when pulse-filling ratio is 0.4%. SpO2 error is ±4%, pulse rate error is ±2 bpm or ±2%(select larger).
- Resistance to surrounding light: The deviation between the value measured in the condition of man-made light or indoor natural light and that of darkroom is less than ±1%.
- It is equipped with a function switch. The Oximeter can be powered off in case no finger is the Oximeter within 5 seconds.
